If you tap in for the FP at 1:35 unless there is some unforeseen back-up in the FP line, you should be fine. Mine Train and BOG are very close to each other in the park.
ETA not sure if you were looking for whether that is doable with SDMT after lunch. Your grace period for the FP would be 2:55. I've never eaten lunch at BOG, so I don't know if finishing in an hour is reasonable. I would try to do the ride before lunch, then you don't have to worry about rushing.
